Let the stream decide what to do with the Unicode object (e.g. it would probably encode the Unicode object using the .encoding and only then write it to the outside world). -- Marc-Andre Lemburg CEO eGenix.com Software GmbH _______________________________________________________________________ eGenix.com -- Makers of the Python mx Extensions: mxDateTime,mxODBC,...
